Application filed July 11,1904. Serial No. 216,044.

To It w/wm, it may concern.-

Be it known that I, BENJAMIN F. B nLLows, a

citizen of the United States, residing at Cleve land, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful improvement in Elevator ll lechanism for Oirculating-lllatrix Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying d ra w i n This invention is an improvement in machines for casting type-bars; and it relates to the mechanism whereby the lines of matrices are transferred from the casting mechanism to the distributing-rail of such a machine. in many of its essentials the mechanism constituting the present invention resembles the mechanism for the same purpose which is shown and described in my prior patent, No. 598.408.

The object of this invention is, generally speaking, to so modify and supplement that mechanism that it will be more durable and more efiieient and certain in its operation.

In the drawings, Figure 1 is a front elevation of as much of a type-bar-making machine as is necessary to disclose the present invention and its relation to the other associated parts of said machine. Fig. 2 is an elevation Fig. 3 is a front view of the lower part of the mechanism in which the present invention is embodied. Fig. 4 is a sectional side view of the mechanism shown in Fig. 3 viewed in the direction of the arrow A. Fig. 5 is a front view of the upper part of the mechanism embodying, the invention when the elevator is down. Fig. 6 is a sectional side view of the mechanism which is shown in Fig. 5 viewed in the direction indicated by arrow B. Fig. 5 is an upward continuation of Fig. 3, and Fig. 6 is an upward continuation of Fig. 4. Fig. 7 is a full-sized front elevation of the upper part of said mechanism when the elevator is in its highest position. Fig. 8 is a horizontal section on line C O of Fig. 7. Fig. 9 is a left side view of the mechanism shown in Fig. 7.

Fig. 10 is a right side view of the same mech an ism.

Extending up from the part of the machine on which the elevator rests when in its lowest position to a point above the distributingrail 1 is a vertical post 2. which is embraced by the elevator 3, for which it serves as a guide. The elevator has on its rear side a matrix rail or shelf 4:, onto which the matrices are placed when the eletator is in its lowest position, at which time said elevator rests upon a part of the machine fra1'ne. The elevator is attached to the ends of asprocketchain 5, which runs under a sprocketwhcel 6. placed below the lowest position the elevator reaches, and over another s;wocketavheol, '7, mounted above the distributing-rail on a fixed part of the machinc 'frame. The upper sprocket always runs idly, but the lower sprocket loose on a rotating shaft 8, to which it may be clutched whenever it is desired to lift the elevator.

Behind the upper part of the post). and parallel thereto is a bar 9, in which the rack-slide 10 is guided in a vertical path. Another horizontally-movable rack-slide, 152, is mounted in suitable guides behind the distrilmting-rail, and both of these rack-slides engage with a freely-rotatable pinion 15, whereby the up ward or downward movement of slide ll) rotates the pinion 13, which thereby causes slide 12 to move. respectively. to the left or right. Secured to slide 1). is a push-bar '18, which extends forward into a plane a little above the distributing-rail.

it is the upward movement of the elevator which lifts slide 10. because the elevator arries a latch in the form of a hook-lever it, which may project beneath a spring-pawl ll, pivoted to the front side of slide 10, near the lower end thereof. On the inner face of a flange 15, which projects rearward from the post 2, near its lower end. is a mun-groove 16, into which friction-roller 17. mounted on the lever 14:, projects, whereby as the elevator goes down the lever is moved forward and the hook thereof is drawn into the ell ator and is there hold while the elevator is down. This grooved flange 15 only extends a short distance above the elevator when it is down. At a point near the lower end of the slide 10 'gravity to its rest position.

this flange again appears, and on its inner face is the cam-groove 19, which engages with said roller 17 and pushes this latch-lever outward as the elevator goes up, so that the hook thereon is moved beneath the spring-pawl 11 on slide 10. Thereafter as zhe elevator continues its upward movement it carries the slide up with it until the slide has moved up so far that the accompanying movement of slide 12 has carried the push-bar 18 over to the left of the path of the elevator. Then the cam-groove 19 on flange withdraws the latch-lever and frees the slide. At that time, however, the slide 10 has reached a point where a spring-pawl 20, mounted on the bar 9, enters a notch 21 in the rear side of the slide 10 and prevents the slide from dropping. This spring-pawl is attached to a rock-shaft 22, having an arm 23, which projects into the path of a pin 24 on theside of the elevator.

After the slide 10 has been released by the elevator and is being upheld by the pawl the elevator continues its upward movement until its rail 4 is just a trifle above the distril: uting-rail1. At that instant the lower sprocket 6 is disconnected from its shaft through the operation of mechanism to be described presently. Then the elevator settles back onto a spring-pawl 25, pivoted to bar 9 and projecting into a notch 26 in the rear side of the elevator, the rail of the elevator being then in line with the distributing-rail. Just as the elevator reaches its highest point the pin 24 thereon strikes the arm 23 and moves it, thereby withdrawing the pawl 20 from its engagement with the notch 21 in slide 10. This slide being thus released falls, thereby turning the pinion 13, whereby the slide 12 is moved to the right. The push-bar 18 thereon sweeps the matrices from the elevator onto the distributing-rail. Just after this has been accomplished a cam 27 on the descending slide 10 strikes the tail of the springpawl and withdraws said pawl from the notch 26 in the elevator, whereupon the elevator falls by During the downward movement of the elevator the hooklever 14 will strike the spring-pawl 11; but

because said pawl is movable it is pushed aside by the hook-lever; but the spring returns the said pawl to its normal position in the path of said hook-lever.

The elevator carries a dash-pot 28, which passes over a fixed plunger 29 just before the a collar 33 on said plunger-rod above the loop, with which the loop engages as the slide goes up, thereby withdrawing the plunger. There is another collar, 34, on the plunger-rod below the loop, and between it and the loop is a leather buffer hen the slide 10 is released, it falls rapidly until the loop 32 thereon strikes the collar 34, or rather the buffer 35 resting thereon, whereupon its downward movement is checked and it is'compelled to move slowly for the remainder of its downward movement.

The clutch 36, by which the lower sprocket 6 is attached to shaft 8, may be of any suitable constructionas, for example, a jawclutch, as shown. This clutch is moved to connect and disconnect the sprocket and shaft by the action of a bell-crank fork-lever 37, which is connected by a link 38 with the armatureframe and a pair of alined electric magnets 40 41. This armature-frame is a rigid structure, of which the ends 42, to which the armatures 44 45 are attached, are rigidly connected by rods 43. When, therefore, either magnet attracts its armature, the frame moves bodily. The circuits of these two magnets are normally incomplete, but means are provided for completing said circuits at the proper time to throw the clutch in either direction. An electric generator 46 of any suitable construction may be connected by wire 47 with the metallic frame of the machine. A wire 48 from the other pole of the generator is connected with an insulated contact-plate 49 in 'a switch-box 50, attached to the framework of the machine near the upper position of the elevator. (See Fig. 10.) There are two insulated contactplates 52 53 in said switchbox on opposite sides of the plate 49. A two-arm switch-lever 54 is secured to but insulated from a pivoted rocker 55, and the two arms of this switch are adapted to electrically connect the plate 49 with either of the plates 52 53. depending upon the position of said switch. The rocker is provided with a finger 56, which enters a notch in a slide-bar 58. A spring 59 moves this bar in one direction, and, in so moving, the bar moves the switch-lever 54 so that it contacts with plates 49 and 52. This is the normal position of this switch. One

other side of magnet 41 is always connectedwith the machine-frame by wire 62. The other wire, 67, of magnet 40 is connected with two insulated plates 63 64. In the machine there are several rotating shafts which have other functions than those connected with the movement of the elevator. To one of these and therefore if no other connection were provided between magnet and the frame of the machine the clutch might not maintain the position into which it had been moved. ilinother connection is, however, provided by means of the insulated plate 64. Adjacent to this plate is a pivotedlever 71, made of metal, which is not insulated from the machineframe. This switch-lever has an arm 72, which enters a notch in the armature-frame. When this armature-frame is moved up, as it is when the circuit of magnet 40 is first completed, this switch-lever is moved into contact with plate 64, and thereby the circuit of magnet 40 is completed through another path. Now when the elevator has nearly reached its highest position an inclined flange 69 thereon engages in a notch 70 in the bar 58, thereby moving said bar in opposition to its spring, with the result of so moving the switchlever 54 that its two arms will be brought into contact with the contact-plates 4:9 and 53, as shown in Fig. 10. This breaks the circuit of n'iagnet 4:0 and completes the circuit of mag net 41, which magnet by moving the armature-frame down withdraws the clutch and disconnects sprocket-wheel 6 from shaft 8. When, therefore, the elevator is released by pawl 25, it is free to fall, the sprocket-wheel 6 running idly on shaft 8 while it is falling.

It will be understood that the precise con nections shown by which the circuits of the ll'lflgllG-ES are completed and broken may be varied. It is desirable, however, that the elevator itself as it reaches its highest position shall cause the movement of an electrical switch or switches by which the circuit of one magnet is broken and the other magnet is completed and the sprocket-wheel 6 thereby disconnected from shaft 8.
